and a quick question here. since escort owns beltronics, and the STI driver is immune to all RDD's. why didn't escort incorporate that technology into the 9500i? the STI was out before the 9500.

It all has to do with marketing. Both in terms of the individual buyer and the retailer. But I wouldn't be too surprised if an Escort brand detector with the RDD invisibility started development.
Escort and Beltronics are the same company, the name "beltronics" is only used as a name now. The company is called "Escort manufacturing" or something like that.

To some of the otehr questions, yes radar can be used on the move in your direction, or opposite. Lazer on the other hand is different. They have to be stationary and can't aim through windows. Rain and fog greatly decrease the range of lazer. There is also a slight cosine error in the lazer reading the further away the target is.

So today, I go to get my power cord and **** outa the glove box and the fuse and the ****ing screw thing blew apart. I put it back together but its ****ed. I guess I'll just have to get a hardwire kit now and do that.
